Poo, Urine and Much more
As it turns out, poo and urine aren’t the only things you need to worry about when swimming inside a pool. Traces of DEET, a chemical commonly used in insect repellants, TCEP, a type of flame retardant, and caffeine have all been found in pool water. Not only that, but pool water has also been found to contain traces of various pharmaceutical drugs, such as ibuprofen, naproxen, and even acetaminophen.
